WINDOW ATTAGHMEN T.

Application filed August 17, 1926.

This invention relates to builders hardware and more particularly to anattachment adapted to be applied to a window sash and limit the extentto which a window may be opened, when the attachment is in operativeposition.

A main object of the invention is to pro vide an attachment which whenapplied to an upper sash and adjusted to engage a lower sash may not bemoved out of position to engage the lower sash until both sashes arecompletely closed. This makes it impossible for a person to release thefastener while standingoutside a window.

Another object of the invention is to so construct the attachment thatit may be firmly applied to an upper sash and when in place will not beunsightly. I

Another object of the invention'is to pro vide an attachment of thischaracter which may be'stamped from sheet metal and therefore verycheaply produced.

The invention is illustrated in the accompanying drawings, wherein,-

Figure l is a view showing a portion ofa window in elevation with theattachment applied to it, and disposed in an inoperative position.

Figure 2 is a sectional view taken on the line 22 of Figure 1, theattachment being shown in the inoperative position in full lines, andits operative position being indicated by dotted lines.

Figure 3 is an enlarged transverse sectional view taken along the line 33 of Figure 2, with the attachment shown in the operative position, and

Figure 4 is a perspective view of the attachment.

The attachment constituting the subject matter of this invention isintended to be applied to a side stile of an upper window sash 1 andwhen in an operative position engages the upper edge of a lower sash 2so that the window may be opened for ventilating purposes without dangerof a burglar 01' other unauthorized person entering a house through anopen window. The bracket 3 which constitutes the mounting element of theattachment is formed of strong sheet metal. The bracket fits against theside stile of the upper sash, as shown in Figures 2 and 3 and isprovided with upper and lower side tongues 4 and 5 which projecttransversely therefrom for overlapping engagement with the inner face ofthe stile. A

Serial No. 129,832. 7

tongue 6 is cut from the upper portion of the bracket opposite thetongue 4 and is bent to project transversely from the stile. The tongue,6 constitutes an abutment adapted to be engaged by the leaf 7 andprevents the leaf from being swung upwardly and toward the glass of theupper sash beyond a substantially vertical position. Referring to Figure4, it will be seen that the leaf 7 which is also formed of strong sheetmetal is pro vided at its free end with a side arm 8 which projectstransversely from the leaf and is cut and bent to provide a lip 9extending transversely from the arm.

WVhen the attachment is applied to the window, the bracket is firstplaced against the stile of the upper sash a sufficient dis tance aboveits lower edge to permit the leaf '7 to be swung downwardly to theinoperative position shown by full lines in Figure 2. The screws 10 and11 are then put in place and will securely hold the bracket inengagement with the window stile. It should be noted that the lowerscrew 11 instead of being countersunk in the bracket is formed with anenlarged head and serves, not only as means to assist in securing thebracket, but also to pivotally mount the leaf 7.

When the attachment is in place and the leaf swung downwardly to theinoperative position, it does not project outwardly from the upper sashand therefore, either the upper or the lower sash may be freely openedits full extent in the usual manner. Vhen, however, the leaf is swungupwardly, to the operative position indicated by dotted lines in Figure2, the arm 8 projects from the upper sash, as shown in Figure 3 andtogether with its side lip 9 extends in overhanging relation to theupper edge of. the lower sash. The lower sash can then only be opened,until it contacts with the armand lip. In actual practice the distancethe lower or upper sash may be opened when the attachment is in anoperative position is about nine inches, and will afford ampleventilation, but prevent any one from stepping into a room through thewindow. In view of the fact that the leaf, when swung downwardly to aninoperative position, has its lower free end disposed very close to thelower end of the upper sash it will be readily seen that it can not bemoved to an inoperative position until both of the sashes are completelyclosed. Therefore a burglar would be prevented from reaching into aclaim room from the outside and releasing the latch. Vihile anattachment has been shown applied to only one side ofthe window, it willbe obvious that a similar attachment could be applied to the other sidethereof ifso desired.

Having thus described the inventioi'i, I

1.. A window fastener comprising a bracket adapted to be secured againstthe inner side face of aside stile of an upper sash, and a leafpivotally connected with said bracket for vertical swinging movement andprovided with an arm extending transversely therefrom, said armprojecting towards the glass of the upper sash out of the path of alower sash when the leaf in a lowered position and extending outwardlyfrom the upper sash into position to engage the upper edge of the lowersash and limit sliding of one sash relative to the other when the leafis swung upwardly.
